Soil Nail Walls – Design and Construction: Day 1
October 21 @ 8:30 am - 10:30 am MST
Soil nailing technology is very versatile and has been widely used worldwide over the last 3 decades for temporary and permanent excavation support. The design and performance of soil nail walls is intricately linked with its construction procedures. To avoid adverse performance issues, design and construction processes for a soil nail wall must be tailored to specific geometry and the environment (conditions) expected over its specified lifetime. This workshop will help gain a better understanding of the design and construction procedures using concepts of limit states that will be indexed to the latest guidelines based on the Load and Resistance Factor Design (LRFD) methodology of the American Association of State Highway Officials (AASHTO) and Federal Highway Administration (FHWA). Contrast between LRFD and the Allowable stress design (ASD) methodologies will also be included. Design and construction (including field testing) aspects of Solid Bar Soil Nails (SBSNs) and Hollow Bar Soil Nails (HBSNs) will be discussed.
